I felt it was about time to check my leisure batteries' fluid level, actually I've been meaning to look at them for quite a while now. As I've got 4 of the blighters it was going to be a long job especially as they're a bit tucked away

I obtained a special tool off eBay which arrived in today's post. A wide bladed screwdriver won't do the job as the slot is wide and rounded. A slight mistake d was needed to make it fit the Banner batteries snugly.

4 batteries, 6 cells to each meant 24 to inspect. Not too soon by the look of things, one battery was rather low.

Fortunately I always keep a 20litre container of distilled water to hand as I only use it with antifreeze, not tap water. I've also got a "dest. wasser" bottle to dispense it without too much mess.

Each battery needed a total of 2 bottles of water, perhaps 500/600ml. I think I'll check them a bit sooner in future

Do you check yours?

Banners are notorious for needing topping up, especially if on permanent charge on EHU or solar, though until recently lots of dealers (and Banner) implied otherwise. They're also a right b*gger to open unless you have the proper tool (which is often hard to find online). Frankly I'd never have another Banner.

Interested to know where you get your sulphuric acid from and what percentage to add to each cell. I believe the concentrate should be diluted to approx 35%, so how do you calculate how much acid to add to each cell?

I'm not sure you need to add acid. Surely when a battery gasses in use it is the water splitting into oxygen and hydrogen that is lost and then you need to replenish it. The H2SO4 doesn't dissociate, it just becomes more concentrated.

Sean, you're right about needing the special tool. I got a Yato battery cap tool off eBay and then narrowed it a touch to suit the Banner cap. That cost me £9.99 whereas the correct Banner tool runs around £28. Don't try to loosen them with a wide blade as they are cheese soft.

We've got a Banner in our bus and it "burns" around 500ml of water a year!
As for removal of the caps our tool cost us 2p!  A two pee piece and a set of mole grips (from stock).[smile]
It's pushing on for six years old and got it checked when getting the cambelt changed a couple of weeks ago and it's down to around 30% so looking around for a new battery.  Probably not another Banner and have been looking at -

https://www.tayna.co.uk/leisure-batteries/varta/lfd90/

Won't necessarily be from this supplier as will be shopping around.

Since starting this MoHo malaraky we have always used Alpha batteries on Ebay, and gone for the cheapest 125ah option, one set was in 4 different vans with no trouble at all, I figure why pay more, I know there is a lot of info out there on which are best, but they are not that expensive so I don't worry about it.

I'd go for a Yuasa 100AH EFB  and my second choice would be a Varta 90AH LFD 90, but only if they couldn't supply my first choice. Allan of aandacaravanservices has a good battery page HERE.

NOTE: Both these batteries are also available from  Alpha Batteries. I have no connection with either company, apart from being a customer.

This is a brilliant idea and I rushed out and checked my one-year-old (Banner) batteries about which there is a long thread somewhere.

However my caps wouldn't accept a 2p but a 1p fitted perfectly so an even cheaper tool [smile]

First thing is open cell batterys as a rule are ok if outside in a top vented box,best is a sealed type as others have said varta/bosch silver powerframe,just dont cycle them down to far and they will hold for on 5 years without voltage drop,normal led acid batts go down hill from the day there filled.
All open batts should be looked at every two/four weeks if in heavy use and charged at a high rate,if not using a standing float charge/auto multi charger will stop gassing but do still eye them over,sealed units are ok to leave and thats why we should be using them in our vans.

Thanks for the input guys.[thumb]  Much appreciated.
At the moment leaning towards Varta or Yuasa.
Anybody had any dealings with Battery Megastore?  Will be heading past Tewkesbury in a week or two and thinking I could pop-in and collect a Varta for around £96 (they don't do Yuasa) with a saving of around £25 over the best price for that brand albeit delivered.

I think Yuasa, Varta, and Exide are the only ones I can recall from my yoof, so at least they have a track record.

Exide still going too.
